3. CONFIRMATION OF S1S60000 STATUS

S1S60000 may issue the event status to inform the host CPU of IC status. The host CPU reads the event status

and option parameters to confirm which event has been informed. This chapter describes how to read the status

option parameters through reading the event status and option parameters by generating a cable disconnection

event and connection recovery event by disconnecting and connecting the Ethernet cable.

The status option parameters are data added to the status. After reading the status, read them from the data port.

When the status option parameters are set, the HINT pin becomes active and bit1 of the flag port is set to "1".

Please confirm that bit1 of the flag port is set to "1" without fail before reading the data row.

In the same manner as the procedure in 3.1, read the "cable disconnection" of the "event" status by actually

disconnecting the LAN cable.

When you disconnect the LAN cable, the "event" status is issued. Read the status in the same manner as "2.

CONFIRMATION OF S1S60000 BOOT". Then, the "event" status (0x000a) can be read. The "event" status is

provided with 16-byte status option parameters; read them from the data port. When S1S60000 and the host

CPU is 8-bit connected, the parameters are read 16 times, and when 16-bit connected, they are read eight times.

For more information about the "event" status, refer to the "S1S60000 Series Host Interface Manual - 3.11

event status".

In the case of "cable disconnection" with the LAN cable disconnected, the following data row can be read.
